Well, then you are stating that Grace is sovereign grace, which means that it is irresistable,.
Free grace (regarding salvation) is just that 'free' in that it is a gift (Rom.6:23), but like any gift, it can be rejected as well as accepted.
Christ cried out for anyone who thirsted to come to Him in Jn.7:37 (see Isa.55), but few come because they reject that grace.
Now, according to Calvinism only the elect receive the grace of faith, based on a sovereign election, a faith which cannot be rejected.
